Investors

On February 28, 2011, Amerigon and our wholly-owned subsidiary Amerigon Europe GmbH entered into a Share Sale Purchase Agreement (the “SPA”) with shareholders to acquire W.E.T. Automotive Systems (W.E.T.), a publicly-traded German company located in Odelzhausen, Germany.

Under the terms of the agreement, Amerigon has agreed to purchase 76.6 percent of the voting shares at a price of euro 40 per share, or $56 per share. Concurrent with this transaction, Amerigon launched a tender offer for the remaining voting shares of W.E.T. at the same price. Based on the 3,040,000 voting shares in W.E.T., the transaction values W.E.T. at euro 121.6 million or $171.3 million. The euro 40 price for W.E.T. shares is a 52 percent premium over a volume-weighted average trading price of W.E.T.'s shares over the three months prior to the SPA of euro 26. Amerigon has secured all necessary financing in order to complete the transaction.

Simultaneous with the execution of the SPA, we and Amerigon Europe also entered into a Business Combination Agreement (the “BCA”) with W.E.T. setting forth the terms and conditions under which Amerigon Europe is required to launch a tender offer in Germany for all of the outstanding shares of W.E.T. (the “W.E.T. Tender Offer”) as well as the terms and conditions governing our and W.E.T.’s conduct prior to and after the closing of the W.E.T. Tender Offer.

Among other things, the BCA provides that W.E.T. shall continue to be operated as a separate business and remain a separate legal entity and subsidiary of Amerigon Europe, including following completion of the W.E.T. Tender Offer, unless certain conditions are satisfied. In addition, W.E.T. management shall remain substantially unchanged up to and until the occurrence of certain conditions specified in the BCA. Moreover, upon the occurrence of such conditions, the current chief executive officer of W.E.T. shall be appointed to the board of directors of Amerigon, subject to compliance with applicable law.

As of May 3, 2011, the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), relating to Amerigon’s previously announced acquisition of a majority of the voting shares of W.E.T. Automotive Systems AG, a German company (“W.E.T.”), has expired without further action by the Federal Trade Commission, thereby satisfying a condition of closing of the transaction. Amerigon and W.E.T. have also received regulatory approval from the Ukraine, which was also a condition to closing the transaction.

The purchase and the tender offer have the approval of the Supervisory Board of W.E.T. and of its Management Board.

General Public

The pending acquisition of W.E.T. is an important strategy for our company, as we become better positioned to meet the needs of the global automotive market. Bringing together the complementary assets of the two companies will allow us to become a more competitive supplier and will enhance our ability to develop more effective products and to improve customer satisfaction.

Amerigon is looking forward to working with W.E.T. as a partner, leveraging the talents and strengths of both companies to best service our customers. Amerigon anticipates little change in the organizational structure of either company during the integration process, as both have been working at an efficient and effective level of operation prior to the acquisition.
